Discord will not work on xfinity internet

I'm currently having issues with my discord applications for PC and mobile. I've discovered that using cellular data for discord allows my application to work.

I've tried:

1. Connecting directly into the modem, and my PC Discord doesn't work

2. Restarting both systems.

3. Reinstalling for both systems.

4. Tried flushing/resetting DNS configurations on PC

5. Anything involving changing Discord options and settings.

But I'm really stumped as to why in the past 3-4 days Discord no longer works on my internet.

There was a forum post about it two months ago with no solution posted. This can be found here:
